What are DLL files?
DLLs are dynamically linked library files. DLL file contains a list of certain functions that can be used by various applications. Spool32.dll is a great example of how the things work: that file is used by various programs for print control within Windows 95 and Windows 98.
Why is it important to unregister malicious DLLs?
DLLs may contain information essential for a computer to function properly. Malicious programs may corrupt regular DLL files or they may install new DLLs instead of normal ones.
Deleting DLLs is a risky deal since it can affect computers performance and functionality of many applications. If a malicious DLL is somehow used by a regular application and the DLL file is removed, the application won't work normally even if the deleted DLL is not needed for a program to function. This is why you have to unregister DLLs before deleting them.
How to unregister malicious DLL files?
a) Open Command Prompt window
Click the "Start" button and select "Run" option. Type "cmd" into the "Open" field and click the "OK" button.
b) Unregister malicious DLL file
Type "regsvr32 /u filename.dll" into the Comand Prompt window and click "Enter". "Filename.dll" should be the name of DLL file you want to unregister
